DRAlN DEVICE.

Application filed May 11, 1925. Serial No. 29,412.

This invention relates to a drain device,

. such as is placed in floors to drain off the water thereon and to which other drain pipes, such as the drain pipes from a sink,

drinking fountain, or refrigerator may be connected.

It is an object of this invention to provide such a drain device having a simple and efficient means thereon by which it can be supported on a concrete slab in the floor or other means, and the cement or other flooring can be placed'thereabout and in contact therewith.

It is a further object of the invention to provide such a drain device having a central opening therein through which the liquid flows together with a dirt catching device about said opening, said device having a perforated cover at its top, said cover being iniperforate at the portion aligned with said opening.

It is still another object of the invention to provide such a drain device comprising a casing having a discharge opening therein below its top and a dirt catching means about said opening and also having spaced portions at its sides to which drain pipes may be connected, said dirt catching portion being disposed below the opening in such drain pipes.

It is also an object of the invention to provide a drain device comprising a casing having a discharge opening therein below the top portion thereof and having avalve casing supported therein, which valve casing carries a float valve co-operating with a seat adjacent said discharge opening and said valve casing also having a discharge opening at. its bottom `with which said float valve co-operates.

It is still another object of the invention to provide a drain device comprising a casing and having a valve casing disposed therein below the top thereof, said valve casing having an inlet opening at its top and a discharge opening at its bottom, said first mentioned casing having a flange surrounding said valve casing having its top portion disposed a considerable distance above the bottom of said valve casing, the wall of said first mentioned casing being spaced from said flange and having `a discharge opening in its bottom, whereby the liquid flowing through said drain device must pass out at the bottom of said valve casing, then pass up over the top of said CII flange and then downward around said flange to the discharge opening in said iirst mentioned casing.

These and other objects and advantages of the invention will be fully set forth in Y the following description made in accordtrated, the same is shown as substantially n A cylindrical having a rounded bottom which has a central projecting hub eta provided with an interiorly threaded opening 4th forming the discharge opening of the device and to which the drain pipe will be connected, which will lead to a sewer or other drain means. The casing 4 is adapted to be set into a iioor and to have its top flush with said floor or other surface to be drained, and said casing is provided a short distance from its top with an outwardly extending liange llc. The casing also has projecting therefrom hubs 4d and 4e, illustrated as being disposed at opposite sides vof 'the casing, which hubs are interiorly threaded to receive drain pipes, such as the drain pipe of a refrigerator or the drain pipe of a sink, or drinking fountain. It will be noted that the flange 4 is disposed substantially cen trally of the hubs 41d and 4e in a vertical direction. The casing 4, as shown, is hollow and has a narrow inwardly projecting flange if at its top, which isrecessed to form a shoulder for receiving a top cover plate 5 flanged to fit into said recess and to fit within the flange 4f, the top of said cover being flush with the top of casing 4f. The cover 5 is provided with a multiplicity of perforations 5a, as shown in Fig. 2, and while these perforations may be of any desired form and arrangement, in theembodiment of the invention illustrated, lthey are shown as segments of annular slots radially arranged. The cover 5 is heldin place by suitable countersunk screws GQ extending therethrough into the flange 4I so that the cover may readily be removed by removal of said screws. It will be noted that 'the central portion of coveriplate 5 is imperforate and this imperfoiate portion is disposed over the central ydischarge opening adjacent the top of casing 4 to be later described. A short distance below the top of casing 4 the same, is provided with an inwardly extending flange 4g kforming a central opening and a valve casing 6 is dis` posed in this opening and extends downwardly quite a distance in casing 4, sai-d valve casing having a top flange 6L resting on the flange 4g. A gasket will be disposed between flanges 6a and 4g and flange frl is' secured to the i'iange 4? by cap screws '7, which screws, it will be noted, do not pass entirely through the flange 4g. The valve casing 6 has accntral opening at its top an-d a inember 8 is disposed Vin this opening, which member is formed as a shell or an open cylinder, andwhich has its bottom portion flaredto form a valve seat. The portion 8 has a flange 8a adapted to form a gasket, and a dirt catching member 9 having a Central opening, aligned with the opening through member S, has a fiange overlying the flange 8" and secured to the top of valve casing 6 by cap screws 10.` The member 9 has a short upwardly extending flange or central portion contracted toward its upper end and the top surface of member 9 is disposed'a short distance below the bottom of the inside of the drain pipes ll and l2, which are received in the hubs 4d and 4e, respectively, sai-d pipes being indicated by dotted lines in Fig. l. The valve casing 6 has a Centra-l opening in its bottom, the sides 6b of which are formed on a bevel to con-. stitute a valve seat, and a float ball valve l? is provided in the valve casing adapted to co-opera'te with the seat 6b and withv the seat formed at the lower portion of member 8. rlhe casing 4 has a flange or wall 4h extending about and spaced from the valve casing 6, the top of which is shown as disposed a short distance above the vertical center of the valve casing 6. As shown in Figs. l and 3, the flange 4h is connected 'to the wall of casing 4 by spaced radially extending ribs and it will be noted, as -shown in Fig. l, that the flange is space-d farthervfroin casing 6 at its bottom portion than at its top portion. An annular chamber is thus formed between flange 4h and casing 6, which cham` ber extends beneath casing 6. lt will also be noted that flange 4h is spaced from vthe wall of casing 4, so that an annular chamber 4j is formed between said flange and sai-d wall with the bottom of which latter annular chamber, the opening 4l communicates.

, The flange 4h has a central threaded opening atgits bottoni normally closed by a plug 14 flange 4h.

threaded therein, which plug has an angulai' recess 14a in its` top adapted toy receive a wrench for turning and, removing the saine.

It will be noted that lthe opening in the top and bottom of valve casing 6 and opening 4bare axially aligned with the opening in the bottom of flange 4h.

ln operation, the casing 4, as stated, will be placed in a floor or pavement with the top thereof preferably flush with the surface of said floor or pavement. rIt is a conimon practice to construct the floors of concrete and the casing 4 can be disposed in an opening` formed in the concrete slab, which is usually a short distance below the top surface of the floor,- the casing being supported on theslab `by the flange 4C. The casing can thus be easily and quickly placed in position and trued up by means ofsaid flange 4C. It will only be necessary to cut small recesses in the slab for the hubs or bosses 4 and 4e. After the casing is prop .erly disposed in position, Athe flooi can be finished with cement or other material, which will be placed in contact with the portion of casing 4 above the flange 4C. The drain water from the floor will run to the device and pass thereinto through the openings -5". It will be noted that the cover plate 5 is impeijforate in the poition disposed over, the ope-ning through member 9, so that the water cannot drop directly into said opening. The water passes into the annu lar trough formed about member 9 and must rise to a level abovemember 9 and run over the edge thereof into valve casing G. Any heavy particles of dirtl or foreign substance will remain in the annular trough and rest on the flange 4g or the flange 6a. As stated, the top of member 9 will Ybe below the bottom of the openings inthe pipes con-l nected to hubs 4d and 4e, so that all liquid will drain outl of said pipes and will not be backed. up therein. The liquid liows in thel valve casing 6 and into the space between. the valve casing and flange 4h. After the liquid fills the chamber in side of flange 4h. it will run over the top edge thereof'into the chamber 4j and will then pass out into the drain pipe through opening'4". The area of the annular chamber between flange 44 and casing 6 is larger than the ai'ea of the openings through valve casing 6, so that ample space is provided for the discharge of the liquid, and there will be no tendency for the` liquid to fill up the drain and back up into valve casing 6. The liquid will be maintained 'in the drain at a level, as indi.-L

cated in Fig. l, horizontal with the top of K Theballvalve 13 will normally float at this level, so that the openings at the top andv bottom of valve casing 6 normallyv are opened. If, for any reason, water shoulfback up from the sewer or other .place through the discharge drain pipe at the bottom of the device, the level o f liquid will be raised from the bottom of valve casing 6 and ball 13 will seat against the member 8 and close the opening at the top of the valve casing, so that the liquid will be prevented from backing up through the drain through the cover plate 5 or into the pipes in hubs 1d and 4:8. If the liquid should dry up in. the drain, the ball valve 13 will rest on seat 6", so that the lower opening in the valve casing 6 will be closed and prevent the passage of gases back thru the drain. Normally, the liquid in the drain forms a seal preventing the passage of gases. The valve casing 6 can readily be removed, when desired, by removing cover 5 and then removing screws 7 The valve casing 6 is of such diameter that it will readily pass through the opening in flange 4g. If it is desired or necessary, at times, to clean the drain pipe, cover plate 5 can be removed, ascan also plug 14. A rod can then be projected through the drain into the drain pipe and reciprocated and moved therein. It may be stated that the member 8 preferably will be made of rubber or similar material. The capacity of the drain is large, one standard size holding substantially three quarts of liquid as against one and one-half pints held in drains of the prior art. It will be noted that there is an air space in the drain above the top of flange 4h. This air space acts as a cushion and also acts to preventsiphoning of the liquid outof the drain casing.V The air in said chamber will breakthe vacuum, so that a Siphon cannot be formed. In drains of the prior art, where the waste opening extends at the side and upwardly, it is a frequent occurrence that the liquidis siphoned out of the drain. The lower opening in the casing is of ample size to take care of all liquid flowing into the casing and the passages about the valve casing 6 are of ample size to take care of any possible discharge through the valve casing. If it is desired to test the water system in a building with the city pressure, it is unnecessary to close or seal the drain, as the ball valve 13 will be forced to its top seat and the drain will automatically seal and prevent the wat-er running out through the top thereof. If the drain pipes are not connected in the hubs 4d and 4f, they will, of course, be closed by suitable plugs.

From the above description, it is seen that the applicant has provided a simple and efficient drain device. The same is easily and inexpensively made and can conveniently be installed in place, and functions efficiently to carry oit the water without any objectionable action. The parts, except the part 8, will be made of suitable metal. The top plate preferably being made of brass and nickel plated. The device is easily and inexpensively produced and the same has been amply demonstrated by long service in actual practice and has been found to be very successful and efficient.
